Re: [libvirt] [PATCH] storage: Fix bugs in VIR_APPEND_ELEMENT series

>From commit id 'd53bbfd1' Found one core and one possible memory leak. Core seen during local virt-test/tp_libvirt run for the vol_create_from test. The memory leak was seen by inspection during a review of all VIR_APPEND_ELEMENT changes In storage_backend_disk/virStorageBackendDiskMakeDataVol(), the 'vol' needs to be kept around since it's used later, so use the _COPY macro. This caused a segv in libvirtd: Program received signal SIGSEGV, Segmentation fault. [Switching to Thread 0x7fffe87c3700 (LWP 6919)] virStorageBackendDiskMakeDataVol (vol=0x0, groups=0x7fffc8000d70, pool=0x7fffc8002460) at storage/storage_backend_disk.c:66 66 if (vol->target.path == NULL) { In storage_backend_rbd/virStorageBackendRBDRefreshPool() there's a failure path where the 'vol' needs to go through virStorageVolDefFree() since it wouldn't be appended.
